It's a hand you can't get away from with his just calling the raise on third and another dead ace. You can't look at it and take him for trips anymore or anyless than him calling the third st. raise with a lesser pair and now aces up. Ask though why you would even raise on fourth.

If he has trip aces then you want to put in the least you can and maybe you fill up since you can't throw away trip K's like this. If he does have aces up why risk a raise scaring him off and knowing you have a set of Kings costing you more profit. The raise on fourth does not appear profitable either way. If you are ahead you might scare him out of the hand early, I mean you did raise on thrid to represent a king and now caught another, so if keen he shoudl be able to surmise you have trip kings. If he does have three aces than he is taking more money.

On fourth I think you had two choices:
1) to see where you are at, raise on fourth to find out if he has trips (again depends on the player) but if he is an astute player he would fold to your raise with Aces up, taking your raise to mean trip kings. When he raises back you get out of there though you have to get out. (I'm assuming you can doubel bet on fourth) You raise and his reraise would have taken you to the river if you just called in value (3BB) so my calling his reraise and deciding to take it to the river you will lose double now if he does have trip aces. So if you choose this plan of action to raise and see where he is act, you have to act accordingly to his response and fold on fourth.

or

2) Figure even if he has three aces you do have trip kings and decide to just call down never raising unless you fill up. If he does have just aces up you made more than if you raised on fourth because he would have folded then. If he does have trip aces you lost less than if you raised on fourth.

Basically I would have just called down from fourth street on. If he has aces up let him pay me, with trips at least i didn't give as much as you did, but knowing the play I may have made a great lay down also because like one poster said he didn't give two craps abotu your paired door card of kings and you raised, I mean did even look at your cards, hesitate. If you KNOW you have trip K to trip A you have a 15% chance to win and should just fold, but that is from the read of your player.
